Abstract:

The ISOLDE Facility at CERN is the world’s leading facility for the production of radioactive ion beams (RIBs) using the ISOL (Isotope Separation On-Line) method. Over 1000 isotopes of more than 70 elements have been produced by the impact of a 1.4 GeV proton beam on a variety of targets and using different ion sources for providing beams at 40-50 keV energy.   Beam purification is achieved through the use of the selective resonance laser ionization process in more than half of the experiments and by mass separation using one of two mass separators.  The isotope/isomer beams can be further accelerated to about 10 MeV/u using the HIE-ISOLDE post-accelerator. 

The low-energy and accelerated beams are used for a wide variety of experiments in nuclear structure research, but also for studying astrophysical processes, for materials properties research, for biochemical and biomedical research and for fundamental interaction studies.

This presentation will give an introduction to the ISOLDE facility and RIB production, an overview of the different experimental set-ups and the many physics questions addressed by ISOLDE experiments, finishing with recent examples of experiments addressing open questions in nuclear and atomic physics.
